This is such a typical old-style news story. They want to write about waitresses dressed as nurses, but that doesn't sound serious enough, so they write about it as a dispute between the restaurant and some nurses.

I bet if you look for headlines in which the subject is plural and the main verb is some variant of "angers," you'll find many are of this form.

I'm not suggesting they're aiming specifically at reddit. Presumably they asked some consultant "how do we get traffic?" and he replied "publish catchy, light articles that will make the rounds of the blogosphere." Being on reddit is just part of making the rounds.
